The circumference around the Earth at different latitudes varies, from 40,075 km at the equator, to 26,291 km at 49° latitude, to 0km at the axis of rotation (i.e. the North and South poles). Thus, as the Earth spins around it's axis, different latitudes will cover different distances within the same time frame. And since speed (and velocity) are calculated by dividing distance by time, the speed (and velocity) will therefore decrease as you approach the poles.

What is the linear speed of earth's rotation at latitude 60 point 24 degrees north?

The linear speed of the Earth's rotation at any latitude can be calculated by multiplying the cosine of the latitude by the equatorial rotational speed of the Earth, which is approximately 1670 kilometers per hour (1037 miles per hour). At latitude 60.24 degrees north, the linear speed of the Earth's rotation would be approximately 835 kilometers per hour (519 miles per hour).


How fast earth rotates on its axis in one second?

The Earth rotates at a rate of slightly over 15 arc-seconds per second.The actual speed of rotation depends on latitude. It's greatest at the equator. At the equator, the Earth's rotation speed is about 465 meters per second.


Is the speed of rotation at the equator greater than that in Canada?

yes. rotation at equator is roughly 1000 mph, rotation at any other latitude is about cos (latitude) * 1000 mph.


How does earth's varying orbital speed affect it's rotation?

The earth's orbital speed has no influence or effect on its rotation.


Is any report that earth rotation speed decreasing?

Earth's rotation speed is gradually decreasing, as a result of the tides.


What is the earth greatest speed of earths rotation?

The speed of rotation is greatest at the equator; 1038 miles per hour.


Where does earth's greatest speed of rotation occur?

At the equator


Is the speed of earth's rotation slowing?

Yes. The energy from the tides ultimately comes from Earth's rotation; due to friction during the tides, Earth's rotation will logically get slower and slower.


Is the speed at which the earth rotates constant?

No. Earth's rotation speed is affected by the gravitational pull of the sun, moon and planets.


How speed of rotation of earth depends on distance between earth and sun?

No dependency, when measured on Earth.


What is the rotation speed of the earth in KM per sec?

Fast.


Does the earth's rotation speed up during tides?

no it just has to do with the position of the earth and moon
